Sletringen (Slettringen) Lighthouse

  •  This light was first established in 1899, and has been automated since 1993. It is located on a small island about 1.5 km (1 mi) west of Titran, the village at the western tip of Frøya. Accessible only by boat. Site open, tower closed.
  • The first light here in 1899 was 65 feet (20 meters) tall. At the same time lights were established on Sandholmen and Kya. All three were established in response to strong pressure from local authorities, pilots, captains and fishermen who were working in the local, rich fishing areas. On the night of October 13–14 of that very year a terrible series of accidents resulted in 29 sunk boats and 140 men lost.
  • The present structure dates from 1923. It is 147.6 feet (45 meters tall) and has a range of 18.5 nautical miles, a focal plane 46 m (151 ft); two white flashes every 15 s; an additional isophase white light is displayed at 31 m (102 ft).
  • The lighthouse is lit from July 21 until May 16 each year. It is not lit during the summer due to the midnight sun in Norway. The lighthouse is also equipped with a foghorn.
  • Sletringen is not only Norway’s tallest, but is the tallest lighthouse in all of Scandinavia.
  • The round cast iron tower with lantern and gallery are mounted on a high, round concrete base and attached to a 2-story keeper’s house. The tower is painted red with two narrow white horizontal bands; base painted white. 1st order Fresnel lens (1923) in use. From the lighthouse a track leads 120 meter down to the boat landing.
  • This is Norway’s tallest lighthouse, not only Norway, but tallest in Scandinavia.
  • This lighthouse has high architectural value with its precise, tight overall building design. The light has high Lighthouse history value as a sample of the iron tower combined with concrete construction. Sletringen is one of the coast’s most spectacular lighthouses.



Titran is a village in the municipality of Frøya in Sør-Trøndelag county, Norway. It is located at the western end of the island of Frøya, about 30 kilometres (19 mi) west of Hammarvika and Sistranda. The village’s economic life is centered around fishing and fish farming. Titran is also known for its windmill energy production. It is the site of the first wind energy production in Norway. Two windmills were built near the village in 1986. The tallest windmill is 32 metres (105 ft) high and can produce 4 MW (5,400 hp). For more, see: Titran.net


  • Frøya is the westernmost part of Sør-Trøndelag county. It is part of the Fosen region and consists of the island of Frøya and several thousand other small islands. The main island of Frøya is connected to neighboring Hitra (and ultimately the mainland of Norway) by the Frøya Tunnel which goes under the Frøyfjorden.
  • The municipality of Frøya has many small fishing communities on small islands in the ocean such as Mausundvær, Bogøyvær, and Sula, with Mausund being the largest of these with a population of approximately 270. Other small islands such as Froan and Halten, Sør-Trøndelag lay to the northeast of the island of Frøya. Many of these islands are home to lighthouses such as Halten lighthouse, Finnvær lighthouse, Vingleia lighthouse, Sula lighthouse, and Sletringen lighthouse.
